NON-CHATTEPI NG BRAKE-HANGER.

SPECIFICATION forming part of Letters Patent No. 762,956, dated June 21, 1904.

' Application filed May 8, 1903. Serial No. 156,245. (No model.)

To all whom it may concern.-

Be it known that I, ROBERT C. TAYLOR, re-

siding in the borough of Brooklyn, in the.

county of Kings and State of New York, have invented certain new and useful Improvements in Non-Ohattering Brake-Hangers, of which the following is a full,.clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same. This invention relates to a suspension device for brake-shoes especially adapted for use in connection with the brake-rigging of a car-truck, but capable of use in a variety of relations. Its object is to provide a link or suspension device which shall bestrong, easily assembled and adjusted, not likely to get out of order, and of a construction tending to prevent chattering of the brake-shoes and strain upon the various parts.

Other objects and advantages will appear and the novel features thereof pointed out in the claims.

In the accompanying drawings, Figure 1 is a View in side elevation of a. truck equipped with my improved link suspension for the brake-heads. Fig. 2 is a perspective showing a detail of the truck-frame and the means for suspending the upper end of the link therefrom. Figs. 3 and i are details'in rear and side elevation, respectively, of a brake- Figs. 5 and 6 are details in side elevation and top plan, respectively, of a hanger.

.Figs. 7, 8, and 9 are details in top plan, side,

and end elevation, respectively, of ahangerblock. Fig-10 is a detail of the suspending belt or link proper. Figs. 11 and'12 are details in section and side elevation, respectively, of a link-sleeve.

Similar reference characters refer to similar parts throughout the several views.

Referring first to Fig. 1, the truck is shown as equipped with wheels A, journal-boxes-B,

frame O, equalizer-bars D, equalizer-springs F, truss-bars F, transoms H, a bolster the side bearing of which is represented at I, and bolster-springs K, all of which parts, as well as various others, the precise construction of which is not specifically claimed, may be of any desired or usual construction, that shown being for purposes of illustration only.

Inasmuch as the suspension device is alike at both ends of the truck, a description of one will sufiice for both, it being understood that there is such a suspension device in connect1on with each brake-shoe and that 1t 18 adapted to be used in connection with a brakebeam if it is so desired.

Brake-shoes 1 are shown as carried by brake heads 2, which brake-heads are shown in detail in Figs. 3 and 4 as equipped with two projecting arms 3 3, extending at an angle to the center line of the brake-head, between which is adapted to be pivoted a lever 4, which may be operated by a rod 5, to which power is supplied in any suitable manner. The lower end of-this lever is connected by link 6 to a similar lever in connection with the other brake-shoe on the same side of the truck, the upper end of this second lever being pivoted in any suitable bracket from the frame, as at 8. As shown, the brake-head 2 is provided with a projecting member 9 in the form of a downwardly-opening. hook, as best shown in dotted lines in Fig. 4c. The T-shaped head 10 of link 11 is adapted to be slipped beneaththis hook and to find a rocking bearing on the under side thereof. .Theupper end of link 11 passes through a hanger 12, (shown in detail in Figs. 5 and 6,) said hanger being adapted to be supported from the frame in'any desired way, as

by bolting it to the transom H and to a gusset 13. The upper face of the hanger 12 is provided with; an open socket, as at, 14, adapted to serve as a bearing for the hanger-block 15, ,thelower surface of which is shaped to fit and have a rocking bearing in the socket 14. The link 11 passes through this hanger-block, and it is adapted to besecurcd in position by ad- ..justingand check nuts 16 17 on the threaded upper end thereof.

The upper face of the curved bearing-arm 9 and the lower face of the hanger 12 below the socket 1a are shaped to present rocking or pivoting surfaces for .correspondingly-shaped ends of a sleeve 18,

which when the parts are assembled, as shown in Fig. 1, loosely surrounds the link 11 and is held between the arm 9 and the lower face of the hanger 12. Hanger 12 for this purpose may be of any suitable construction, but that shown, comprising a casting or web having side flanges, is preferred.

It will thus be seen that I have provided a suspension device for brake-heads which may be easily assembled by placing the link 11in position with reference to the brake-head, placing the sleeve 18 thereon,and then running the end of the link up through the hanger and hangerblock and adjusting it to any desired degree by turning the nuts. The adjustment for all points of wear-that is, to take up slack at all wearing-surfaces between the brake head or shoe and its ultimate point of support'can thus be made at a single point and by asingle operation through the turning of the single adjusting-nut, the use of the check or look nut beingincidental and negligible. While for the purposes of convenience it is preferred that this adjustment should be made at the upper end of the tension member or link 11, it Will be obvious that the construction could be so arranged as to bring the adjusting-point at the lower end of the link or at any other desirable point. It has been found in practice that the provision of a sleeve extending between the bearings of the link or link-bolt is very advantageous in the prevention of chattering of the brake-shoes or loosening of the parts. The sleeve provides what may be termed a compression member, which acts in opposition to the link or tension member,the combined action of the two tending to hold the brake-head securely and prevent chattering or straining. Obviously this member could be made in the form of a sleeve or otherwise to suit the mechanical requirement of the particular structure with which it is associated.

The fact which is especially applicable to devices of the class with which the present invention deals should be obvious that various manufacturers or mechanics might readily modify the details of the construction shown, might substitute elements, and might materially change the appearance of the construction while still availing themselves of the principles and utilities here defined and suggested.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a suspension device for use in connection with the brake-shoes of vehicles, a suspension-link adapted to be pivotally connected to a brake-shoe and to be pivotally supported from the frame, and a sleeve surrounding said suspension-link and extending between the point of support of the link and its point of pivotal connection to the brake-shoe.
